Back Projection
Rear projection (background projection, process photography, etc.) is one of many in-camera effects cinematic techniques in film production for combining foreground performances with pre-filmed backgrounds. It was widely used for many years in driving scenes, or to show other forms of "distant" background motion. Technique Actors stand in front of a screen while a projector positioned behind the screen casts a reversed image of the background.

Some examples of in-camera effects include: * Matte painting * Schüfftan process * Forced perspective * Dolly zoom * Lens flares * Lighting effects * Filtration such as using a fog filter to simulate fog, or a grad filter to simulate sunset. * Shutter effects. * Time-lapse, slow motion, fast motion, and speed ramping. * Bipacks * Slit-scan * Infrared photography * Reverse motion * Front projection * Rear projection * Phonotrope a live animation technique that uses the frame-rate of a camera There are many ways one could use the in-camera effect.
